Start time: 7:15 A.M. Elapsed time: 2 hrs 20 mins End time?

Answers

The time would be 9:35 am

Hi, Mystic0user0!
So the question is asking for the time 2 hours and 20 minutes after 7:15.

It's a lot like adding numbers.

So first add the minutes. 15+20 minutes. That would give you 35 minutes.

Then add the hours. 7+2. That would be 9 hours since there is no carry over from the minutes.

The End Time would be 9:35 AM.

Hope this helps :)

A rectangular prism has a volume of 105 m3. This prism is enlarged using a scale factor of 4. What is the volume of the enlarged prism?

Please Explain...

Answers

The volume of the new prism is 6,720 m³ !

Here's how it works:

The volume of any rectangular prism is (length x width x height).

If you double each dimension, then the new volume is

(2 x length) x (2 x width) x (2 x height) = 8 x (length x width x height) .
That's 8 times the original volume.
Where did the ' 8 ' come from ?
It's the cube of 2 .

In this problem, we multiplied each dimension by 4, so the new volume is

(4 x length) x (4 x width) x (4 x height) = 64 x (length x width x height) .
That's 64 times the original volume.
Where did the ' 64 ' come from ?
It's the cube of 4 .
We didn't really have to figure it out. We knew that if you multiply each dimension
by the same number, then you multiply the volume by the cube of that number.
That's a good thing to remember.

The original volume was 105 m³ .

The new volume is (4³) x (105) = (64) x (105) = 6,720 m³

What is the solution set of the equation x^2-3x-4=6

Answers

Answer:

x = 5, x = -2

Step-by-step explanation:

x² - 3x - 4 = 6

Subtract: x² - 3x - 10 = 0

Find two numbers to factor: adds up to -3x, product is -10x²: -5x and 2x

Substitute: x² - 5x + 2x - 10 = 0

Factor: (x - 5)(x + 2) = 0

Solutions: x = 5, x = -2
